Abstract

Ocular diseases are sub-diagnosed in bird species, partly because of limited diagnostic methods and lack of reference data. Placement of Schirmer tear test strips in the bottom of the conjunctival sac of birds for tear flow measurement can prove to be difficult, whereas paper tips commonly used for dental procedures may be easier to use, due to a more adequate size and shape. Hence, the aim of this study was to assess and compare tear flow values, using ABC Dental® # 30 color paper tips and TearFloTM Test strips in Red-lored Parrots (Amazona autumnalis) (n = 26). Captive birds of undetermined sex were housed in groups under similar environmental conditions and fed the same diet. All animals were deemed healthy through remote and physical examinations. Average tear flow values of 0.6365 ± 0.032 cm/min and 0.5942 ± 0.032 cm/min were obtained with the Schirmer strips test and the endodontic tips respectively. Lack of difference in observed values between measurement techniques (p = 0.3629) indicates that endodontic tips may be a good alternative for tear flow assessment in Red-lored parrots. In addition, endodontic tips are more cost effective and may be less invasive. This study stresses the need to establish species specific ophthalmic reference values for clinical practice in birds, since differences have been reported even in specimens within the same genus.Figure 1.

根管纸点和Schirmer条用于测量红色鹦鹉（Amazona autumnalis）的眼泪流量

眼部疾病在鸟类中被亚诊断，部分原因是诊断方法有限，缺乏参考数据。将Schirmer泪液测试条放置在鸟类结膜囊底部进行泪液流量测量可能很困难，而通常用于牙科手术的纸尖端可能更容易使用，因为其尺寸和形状更合适。因此，本研究的目的是使用ABC Dental®#30彩色纸尖和TearFloTM测试条评估和比较红色鹦鹉（Amazona autumnalis）（n=26）的眼泪流量值。未确定性别的圈养鸟类被分组安置在相似的环境条件下，并以相同的饮食喂养。通过远程和身体检查，所有动物都被认为是健康的。Schirmer条试验和根管尖端的平均泪液流量分别为0.6365±0.032 cm/min和0.5942±0.032 cm/min。测量技术之间的观测值没有差异（p=0.3629），这表明根管尖端可能是评估红色鹦鹉泪液流的一个很好的选择。此外，根管尖端更具成本效益，并且可能侵入性更小。这项研究强调，有必要为鸟类的临床实践建立特定物种的眼科参考值，因为即使在同一属的标本中也有差异的报道。图1。用TearFloTM测试条测量红色鹦鹉的眼泪流量
